About greentech projects

greentech projects is a project developer for large ground-mounted photovoltaic power plants in Europe. We develop projects from the initial idea, all the way to implementation. In so doing, we carry the project development costs, till the commencement of construction and, we also manage the facilities for the long term, after the construction is complete.

At the moment, our core markets are Germany and the United Kingdom. Our teams cover the complete development chain, from site identification, approval procedures and technical layout, all the way to offtake considerations and project financing. On top of that, we also work closely with external project developers and partners, on co-developments.

greentech was founded in Hamburg in 2008 and has subsequently become a leading independent manager of PV plants in Europe.
Our customers include insurance firms, investment funds, public utility companies, and both regional and international utilities.

In 2019, Hamburg-based entrepreneur Erck Rickmers became the majority shareholder of the company. The remaining shares are held by management. greentech therefore combines technical expertise and comprehensive project development know-how with the financial strength of the Erck Rickmers Group.

Our services

As a site lessor, you benefit from attractive long-term leasing income, for up to 30 years.

For suitable sites, we will enter into a long-term leasing contract and take over the realisation of the entire project, from the technical planning and approval procedures, all the way to the construction and financing of the PV facility.

A solar park is also a profitable investment for municipalities, which supports local businesses at the same time.

Solar parks boost the local economy, make sensible use of unused land, and provide additional income for municipalities, for example, through leasing, sales, local business rates and profit taxation.

At the same time, solar parks are an active and measurable contribution towards the climate goals of Germany and the whole of the EU.

Are you looking to sell project rights, or are you in search of a strong partner for effective and long-term cooperation?

We will take on your project rights at any development phase and are prepared to enter into long-term partnerships for co-developments.

You could benefit from both our project experience and our financial strength, which is an important prerequisite for larger projects.
